I personally have thought of a smoothie as a good post-workout option – not a pre-workout meal. However, I see no reason why a smoothie wouldn’t be a great energy boost before a run.

The one slight concern I have is the milk, which is not the easiest thing to digest. If you have any digestion issues with milk, it may be best to cut that out of the recipe and substitute it for something else (water and crushed ice?).
